Rigid Box Luftfilter
A rigid deep-pleat filter that packages a large glass-fiber media area inside a gasketed galvanized box for stable operation under variable airflow.
- Rigid Box Construction
- Deep-Pleat Media Pack
- Stable Variable-Airflow Service
- Gasketed Header Seal
Produkteinführung
The rigid box air filter encloses a medium-efficiency deep-pleated glass-fiber pack inside a galvanized steel frame with a single header or box flange. Aluminum or hot-melt separators hold adjacent pleats apart so airflow reaches the full media depth. Polyurethane sealant fixes the pack to the frame and closes the perimeter against bypass, while a neoprene or polyurethane gasket seals the header to the filter bank. The rigid construction remains stable in air handlers where flexible pockets may move or collapse during rapid airflow changes.
Key Features
Separators preserve uniform channels and stop adjacent pleat faces from touching.
A galvanized frame resists distortion during front loading and variable-air-volume operation.
Perimeter sealant and a replaceable header gasket create two distinct barriers against bypass.
Kunden Produktbedenken
A rigid box filter must keep its media channels open and seal both the internal pack and the external mounting interface.
Flexible filters collapse or flap when airflow changes rapidly.A fixed box frame and supported pleat pack maintain geometry across the operating range.
Deep pleats touch and block airflow through the center of the media pack.Aluminum or hot-melt separators create consistent channels from the upstream to downstream face.
Air bypasses between the pleated pack and the inside wall of the box.Continuous polyurethane sealant bonds the pack perimeter to the galvanized frame.
The filter header leaks against an uneven bank frame after repeated changes.A resilient replaceable gasket compresses around the entire mounting flange.
